Marine
Issued at 645pm EDT Sunday September 25 2022 A Tropical Storm Watch has been issued for the nearshore and offshore waters along and west of the Lower Keys, including the Gulf waters, western Hawk Channel, and the western Straits of Florida. A Coastal Flood Watch is also in effect, with current coastal flooding and high tides likely to be exacerbated by he passage of potential Major Hurricane Ian on Tuesday and Wednesday.

From synopsis, light to gentle east to southeast breezes will gradually freshen tonight through Monday morning, and then steadily freshen Monday afternoon through Monday night, as Tropical Storm Ian approaches western Cuba. Tropical Storm Ian is forecast to rapidly strengthen into a hurricane over the northwestern Caribbean Sea on Monday, then becoming a major hurricane as it reaches the southeastern Gulf of Mexico west of the Florida Peninsula by late Tuesday night or Wednesday morning. While the center of Ian is expected to remain west of the Florida Keys coastal waters, hazardous marine conditions are expected beginning Monday evening. Hazardous seas will likely continue through at least Friday night for the western marine zones, including the Dry Tortugas. Mariners should continue to monitor the latest information provided by the National Hurricane Center and the National Weather Service office in Key West.
